SPECIFICATION forming part of Letters P aea No. 464,364, dated December1, 1891. 7 Application filed January 19, 1891:. Serial No. 378,265. (Nomodel.)

To aZZ whom it mag concern.-

Be it known that I, IRA ALLEN JEFFERSON, of Park City, in the count-y ofSummit and Territory of Utah, have invented a new and ImprovedWind-Engine, of which the following is a full,clear, and exactdescription.

This invention relates to wind-engines, or, as they are commonly termed,windmills, the object of the invention being to provide an engine ormill that shall be especially adapted for use in prairie regions orother places where sudden changes of the air-currents prevail.

To the end above named the invention consists of certain novelconstructions, arrangements, and combinations of elements, which will behereinafter described, and specifically pointed out in the claims.

- Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views.

Figure 1 is a plan view of my improved wind-engine, the parts beingrepresented as they would appear if the wind were light and were movingin the direction of the arrow shown in connection with the figure. Fig.2 is a similar View, the parts, however, being represented as theyappear when a strong wind prevails. Fig. 3 is a sectional elevation ofthe wind engine or mill. Fig. 1 is a sectional elevation of the centralsection of the mill, and Fig. 5. is an enlarged detail view of theregulating attachment.

In the drawings, 10 represents a post or standard, which is providedwith an upwardly-extendingtube or pipe 11, upon which there is mounted asleeveor spider 12, that is formed with a cam-groove 13, in which thererides a slide 14, to which slide there is secured a connecting-rod 15,which transmits the power.

The sleeve or spider 12 carries a number of radial arms 16, to the endsof which arms there are secured vertical strips 17, that carry hoops 18.The sails 20 are pivotally supported between the hoops 18, and theirinward movement is limited by a hoop 21, carried by spokes 22, thatextend radially from ahub 24, the lower edge of said hub being formedwith a series of inclines a, which are complementary to inclines b, thatare formed at the upper end .of the sleeve 12. T0 the hub 24 I connectrods 25, that are in turn pivotally connected to rods 26, which carryweights 27, the rods 26 being in turn pivotally connected at c c ,to theupper hoop 18.

In connection with the parts described I arrange a heavy spiral spring30, one end of said spring being connected to one of the main arms orspokes 16, while the other end of the spring is connected to one of thespokes which support the hoop 21, the tendency of the spring being tothrow the parts to the position in which they are shown in Fig. 1 thatis, to throw the hoop 21 in the direction of the arrow shown at cl.

About the upper portion of the tube 11 I mount a cage 32, which carries.a ring'33, saidv ring being'normally held against a stop-ring 34 by aspiral spring 35. To the cage 32 there is connected a cord or rope 36,which extends about sheaves 37 and 38 to alever 39, that is mounted atone edge of a tank 40, the long arm of the lever 39, carryinga float 41,which, when the water within the tank has reached the desired height,will act to throw the lever 39 as indicated by its arrow, and as thelever..3 9 is so moved the cage will be drawn down, this movement of thecage being designed for a purpose which will be hereinafter explained.

In order that the fans or sails 20 may be controlled and act to bringabout a certain speed of revolution irrespective of the strength of thewind, I provide fingers 50, that are pivotally mounted upon rods carriedby the hoops 18, the inner ends of these fingers passing through staples5l,thatare carried by the hoop 21. Beyond the hoops 18 I arrange anouter hoop 43. If the wind is light, the hoops 43 and 21 serve to limitthe play of the sails or fans, as is indicated, when the parts areaffected, as represented in Fig. 1; but if the wind be strong, so as tobring about too rapid a revolution of the wheel, the governor-weights 27will fly outward, and in so flying outward will draw upon the rods 25,and these rods will turn the hub 24 and cause such hub to rise until itbears against the under face of the ring 33, the frictional contact ofthe hub and ring tending to check the travel of the hoop 21, andconsequently the hoops 18 will travel faster than the hoop 21 for aninstant, and the relative position of the parts will be as representedin Fig. 2, and when the parts are so relatively located the fingers will1 act to hold the sails or fans in a position such that they will be atall times practically tangential to the hoops 18.

If the engine is used for pumping and sufficient water has been pumpedinto the tank 40, the rising of the float Will draw down the ring 33,and the same checking of the movement of the hoop 21 will be broughtabout.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a wind-engine, the combination, with thesail-carrying frame, of pivotally-mounted regulating-fingers, a hoopthat engages said fingers, a spring arranged in connection with thehoop, and a governor by which the motion of the hoop is retarded,substantially as described.

2. In a wind-engine, the combination, with a sleeve, of hoops 18,carried thereby, sails carried by the hoops, fingers supported by thehoops, a hub, an inner hoop 21, carried by the hub, a spring 30,arranged in connection therewith and with the hoops 18, inclines a and bon the hub and sleeve, respectively, and a governing attachmentconnected with the hub, substantially as described.

3. In a windmill, the combination, with the slide 1 1, formed withinclines b and carrying hoops 18, of fans or, sails carried by the saidhoops, fingers 50, also supported by the hoops, a hub 24, havinginclines Co, which rest upon the inclines b, a hoop 21,'carried thereby,a spring 30, arranged as described, rods 25,connected to the hub 24, andlever-arms to which the rods are connected, substantially as described.

"4. In a windmill, the combination, with the slide 12, formed withinclines b and carrying hoops 18, of fans or sails carried by the saidhoops, fingers 50, also supported by the hoops, a hub 24, havinginclines which rest upon the inclines b, a hoop 21, carried thereby, aspring 30, arranged as described, a cage 32, a spring arranged inconnection therewith, a ring 33, carried thereby, a lever connected tothe cage, and a float arranged in connection with the lever,substantially as described.

5. In a wind-engine, the combination of the sleeve 12, provided with thespokes 16, united to the standards 17 with the upper and lower hoops 18,the outer hoop 4:3, and the braces united to the standards 17, wherebycom pactness and portability are obtained, as set forth.

6. In a wind-engine, the combination, with the sleeve 12, provided withthe inclines b, and sails 20, carried by the sleeve, of the hub 24:,provided with the inclines a, a governor connected to the hub, andafriction-ring above the hub, substantially as and for the purpose setforth.

7. In a wind-engine, the combination, with the sleeve 12, provided withthe inclines b,

and the sails 20, carried by the sleeve, of the hub 24, provided withthe inclines a, the pivoted rods 26, connected to the hub, the weightson the rods, and a friction-ring above the hub, substantially as and forthepurpose set forth.

8. In a wind-engine, the combination, with two main frames and sailspivoted to one of the said frames, of an inner frame and fingerspivotally mounted on one of the main frames and connected to the innerframe and adapted to bear against and control the sails,

substantially as and for the purpose set forth.
